MEANS FOR PROPELLING VESSEL-S.

SPECIFICATION forming part of Letters Patent No. 422,129, dated February25, 1890.

Application iiled October 25, 1889. Serial No. 328,147. (No model.)

To all whom t may concern,.-

Beit known that I, 'ABRAHAM I-IEUMAN, of the city, county, and State ofNew York, have invented a new and useful Improvement in Means forPropellin g Vessels, of which the following is a full, clear, and exactdescription.

The invention consists of the construction, arrangement, and combinationof parts, alll as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the fig ures.

Figure 1 is a plan view of a portion of a vessel astern of midshipshaving my invention applied thereto, the deck being broken away to showthe machinery; and Fig. 2 is a side elevation of the saine, a part ofthe hull being broken away.

A represents a crank-shaft jonrnaled in the sides of the-hull B. To theends of this shaft are secured the side-wheel propellers O C.

\ This shaft A is operated by the walking-beam Vrod D.

wheels E, (one each side of the crank A,) which mesh each with a pinionF on shaft G.

vOn shaft G are secured, also, two beveled gear-wheels H, which meshwith beveled pinions J on the shafts J. These shafts reach to the sternof the vessel and are provided at their outer ends each with ascrew-propeller K, so that the same vessel is provided with both systemsof propulsion, each assisting the other, so that a very high speed maybe attained.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, isl The main crank-shaft, to which thewalkingbeam is attached, jonrnaled athwart midships and provided withtwo gear-wheels E-one each side of the crank-and a parallel shaftjournaled below the main crank-shaft, provided with two pinions meshingwith gear wheels E, and provided also with two large beveledgear-wheels, in combination with the screw-propeller shafts j onrnaledat right angles to the main crank-shaft and provided with beveledgear-pinions J, which mesh with the beveled gear-wheels E, substantiallyas described.
